CV/IV Measuring Systems

Electrical Layer Characterization

Mercury contact CV and IV measuring devices from Polytec open up to you the sheer diversity of electrical characterization of a wide range of layers such as oxides, dielectrics, layers on conductive and insulating substrates or of SOI wafers.

The special scan head concept offers you a repeatable and precise, defined contact area variable, combined with outstanding safety and tidiness when handling mercury, the contact material. Depending on the application, you can implement an extremely wide range of contact geometries.

The multitude of possible measurement methods allows you to characterize a wide range of samples, such as.

• Monitoring Oxide Integrity and Quality
• Creating Doping Profiles
• Measuring Charge Carrier Service Lives
• Determining the Resistances of Practically Insulating Materials
• Characterizing SOI Structures
• Examining Ferroelectric Materials
• Characterizing Polysilicon

Rectangular pulses are used to measure the practically static and HF capacities. To name but one example, the advantages lie in the insensitivity to the series resistance.

Connections for existing external HF sinusoidal sources increase flexibility in use.
